How SAFE Sequence CRDT Data Type is implemented

Sequence CRDT: is implemented so that only vaults hold a complete copy of the Sequence

The client also keeps a replica, each operation is made locally and right after broadcasted to the network’s replicas/Elders, this gives you the local-first/offline feature already. Depending on what type of client/app, it may be syncing the local replica with the remote replicas more or less often.

This raises more questions! Presumably that has to be fetched as there is no client side storage AFAIK?

We added a memory storage for keeping the local replica: https://github.com/maidsafe/safe-client-libs/blob/master/safe_core/src/client/mod.rs#L822
